This invention relates to window closers and its principal object is to provide a device adapted to normally retain a sliding window in an elevated position and which will be actuated to permit it to descend to closed position by rain water.

A further object of the invention is to provide a device of this character embodying a movable latch which is normally engaged beneath the lower rail of a sliding window sash and electrically actuated means for disengaging the latch element from the window sash to permit the same to fall, the electrical means being actuated incident to the weight of falling weather.

With the preceding and other objects and advantages in mind, the invention consists in the novel combination of elements, construction, arrangement of parts and operations to be hereinafter specifically referred to, claimed and illustrated in the accompanying drawings, wherein Figure 1 is an elevation of a building equipped with the invention.

Figure 2 is a longitudinal sectional view of the rain actuated circuit closer used in conjunction with the invention.

Figure 3 is a top plan view.

Figure 4: is a fragmentary vertical sectional view of the window showing the relation of the same with the magnetically operated window retaining latch, and

Figure 5 is a fragmentary elevation taken at right angles to Figure 1.

Referring in detail to the drawings wherein corresponding characters of reference denote corresponding parts throughout the several views, the numeral 5 designates a casing adapted to be supported upon the roof or other convenient point of a building as shown in Figure 1 and mounted in the upper end of the casing is a pan 6 whose bottom is inclined as at 7 and terminates in a discharge spout 8 at its lowest end.

An insulating body,10 is disposed upon the bottom of the receptacle 5 and is formed with an end part 11 which is of a relatively great height as compared to the height or thickness of the body 10. A circuit closing bar 12 is pivoted to an L-shaped bracket 13 secured on the upper face of the body 10. This bracket 13 is connected with an electricity conductor 14 which leads to one terminal of a source of electrical energy 15. A pan or receptacle 16 is secured to the upper face of the lever 12 at one end and is located at a point to receive rain water dripping from the discharge opening 8 of the pan 6. A conductor plate 17 is secured to the upper face of the part 11 of the body 10 and is connected with the other terminal of a conductor 18 leading from the electrical supply 15. A contact arm 20 is secured as at 21 to the conductor plate 17 and part 11 of the body 10. This contact arm includes a resilient bowed element 22 that is disposed upon the vertical face of the part 11 and is adapted to be engaged by an enlarged end 23 0f the circuit closing lever 12 to complete an electric circuit as hereinafter described. This enlarged end 23 of the lever 12 is insulated as at 24.

Secured to one of the vertical sides of the window structure shown in Figure 3 is a plate 25 that extends at right angles to the sliding sash S. A U-shaped yoke 26 is secured to this plate and held by this U-shaped yoke is an electromagnet 27 that is included in the circuit above set forth. The armature of this magnet is in the nature of a pivoted window sash engaging element 28 that is normally suspended in a perpendicular position and engages the sash as shown.

When a window is left open during the absence of an occupant of a dwelling or office and it begins to rain, the latter falling into the pan 6 is caught by the receptacle 16. As the latter fills it overbalances the enlarged end 23 of the lever 12 and swings the latter to a position where it will engage the contact 20 to complete an electrical circuit through the electromagnet 27 the latter functioning to draw the latch element 28 inwardly away from the window sash to permit the latter to drop to gravitate to closed position.

While I have shown and described the preferred embodiment of the invention, I desire to have it understood that such changes may be made in the form, construction, arrangement of parts and operations, as will not depart from the spirit of the invention or the scope of the subjoined claim.

What is claimed is:-

A window releasing device of the character described comprising a circuit closer including a casing, a rain receiving pad supported in the upper end thereof and provided with a discharge spout at one end. a nonconducting body arranged in the bottom of the casing and having one end elerated and of a relatively great height, a

pivotedcircuitclosing bar supported on the non-conducting body, a pan carried by one end of said bar and adapted to catch rain Water from the discharge spout a conductor plate secured to the upper surface of the relative high part of the body, a contact member secured thereto and arranged in the path of the opposite end ofthe bar to complete an electric circuit when the bar is overbalanced by the Weight of the rain Water in the pan last mentioned and latch means actuated by the circuit closer for re leasing an open Window.

In testimony whereof I affix my signature.
